<code class="docutils literal notranslate"><span class="pre">moc</span></code> and <code class="docutils literal notranslate"><span class="pre">uic</span></code> files.  As this <a class="reference internal" href="../manual/cmake-qt.7.html#origin-autogen"><span class="std std-ref">The &lt;ORIGIN&gt;_autogen target</span></a> target is created at
generate-time, it is not possible to define dependencies of it using
e.g.  <span class="target" id="index-0-command:add_dependencies"></span><a class="reference internal" href="../command/add_dependencies.html#command:add_dependencies" title="add_dependencies"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">add_dependencies()</span></code></a>.  Instead the <code class="docutils literal notranslate"><span class="pre">AUTOGEN_ORIGIN_DEPENDS</span></code>
target property decides whether the origin target dependencies should be
forwarded to the <a class="reference internal" href="../manual/cmake-qt.7.html#origin-autogen"><span class="std std-ref">The &lt;ORIGIN&gt;_autogen target</span></a> target or not.</p>
<p>By default <code class="docutils literal notranslate"><span class="pre">AUTOGEN_ORIGIN_DEPENDS</span></code> is initialized from

<p>In total the dependencies of the <a class="reference internal" href="../manual/cmake-qt.7.html#origin-autogen"><span class="std std-ref">The &lt;ORIGIN&gt;_autogen target</span></a> target are composed
from</p>
<ul class="simple">

(enabled by default via <code class="docutils literal notranslate"><span class="pre">AUTOGEN_ORIGIN_DEPENDS</span></code>)</p></li>

<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Disabling <code class="docutils literal notranslate"><span class="pre">AUTOGEN_ORIGIN_DEPENDS</span></code> is useful to avoid building of
origin target dependencies when building the <a class="reference internal" href="../manual/cmake-qt.7.html#origin-autogen"><span class="std std-ref">The &lt;ORIGIN&gt;_autogen target</span></a> target
only. This is especially interesting when a
<span class="target" id="index-0-variable:CMAKE_GLOBAL_AUTOGEN_TARGET"></span><a class="reference internal" href="../variable/CMAKE_GLOBAL_AUTOGEN_TARGET.html#variable:CMAKE_GLOBAL_AUTOGEN_TARGET" title="CMAKE_GLOBAL_AUTOGEN_TARGET"><code class="xref cmake cmake-variable docutils literal notranslate"><span class="pre">global</span> <span class="pre">autogen</span> <span class="pre">target</span></code></a> is enabled.</p>
<p>When the <a class="reference internal" href="../manual/cmake-qt.7.html#origin-autogen"><span class="std std-ref">The &lt;ORIGIN&gt;_autogen target</span></a> target doesn't require all the origin target's
dependencies, and <code class="docutils literal notranslate"><span class="pre">AUTOGEN_ORIGIN_DEPENDS</span></code> is disabled, it might be
necessary to extend <span class="target" id="index-1-prop_tgt:AUTOGEN_TARGET_DEPENDS"></span><a class="reference internal" href="AUTOGEN_TARGET_DEPENDS.html#prop_tgt:AUTOGEN_TARGET_DEPENDS" title="AUTOGEN_TARGET_DEPENDS"><code class="xref cmake cmake-prop_tgt docutils literal notranslate"><span class="pre">AUTOGEN_TARGET_DEPENDS</span></code></a> to add missing
dependencies.</p>
